HYDROCARBON-VAPOR BURNER.

' SPECIFICATION forming part of Letters Patent No. 718,675, dated January 20, 1903.

Application filed December 10, 1900. Serial No. 39,429. (No model.)

To all whom, it rnrty concern:

Be it known that I, LEON TAPIN, a citizen of the Republic of France, residing at No. 8 Rue du Poteau, Paris, in the department of Seine and Republic of France, have invented a new and useful Improvement in Hydrocarbon-Vapor Burners, of which the'following is a specification.

The present invention relates to improvements in the operation and construction of lamps for petroleum under pressure provided with a vaporizing-tube.

The characteristic of the invention consists in a special construction of the vaporizer giving great advantages in practice both of operation and economy.

The vaporizer of my invention is formed, essentially, of two tubes united together at a right angle in the form of the letter T. The vertical stem receiving the liquid petroleum at its base is placed parallel to the flame of the lamp and within itsimmediate reach, so that this flame encounters the same branch along its length. The horizontal tube of the vaporizer containsa needle for cleaning and regulating the escapement-orifice for the gas and vapor, which is provided at one end of the tube,'the other end thereof being provided with the mechanism for operating the same needle. According to my invention the horizontal tube containing the needle is connected with the vertical branch at a point so chosen that this horizontal tube is divided into two parts by the vertical tube, one part having the escapement-oriflce for the gas and vapor placed immediately above the flame, the other part provided with the mechanism for operating the needle being beyond the mechanism for actuating the needle (screws, stuffing-box, 850.) and also the handle 5. The first part of this principal tube is placed directly above the flame and Within its reach. The second is altogether beyond the action of the said flame. upon the principal tube in such a manner that it communicates internally with it. At the bottom this branch is connected with the supply of petroleum 6. The preliminary heating of this branch 2 is obtained by igniting spirit in the cup 7, fixed at the bottom of the branch. The petroleum which evaporates in the branch passes into the principal tube and escapes by the orifice 3 as gas and vapor. This gas and vapor enters under considerable pressure into the Bunsen burner 8, mixing there with the air which enters through the holes 9. The combustible mixture is conveyed by the tube 8 to the burner provided with the mantle 10 which isplaced parallel to the tube 2 so that the flame renders this mantle incandescent when placed on the burner 2 and brings it to the high temperature which is necessary for the vaporization of the petroleum in this branch.

It will be seen that my incandescent petroleum-lamp is characterized by the fact that the mantleflame is confined in the angle formed by a portion of the principal tube 1 and by the branch 2, whereas the other part of the principal tube l-that, namely, which carries the mechanism for actuating the needleis well separated from the flame by means of this branch 2.

What I claim is- In a lamp for incandescent lighting by means of vaporized petroleum under pressure, in combination, a vaporizing-tube substantially parallel to the direction of the flame and in contact therewith throughout the greater part of its length, a petroleumsupply tube connected to the base of said vaporizing-tube, a substantially horizontal tube connected toward its center with the top of the vaporizing-tube and so adjusted with regard to the burner that one half of said horizontal tube surmounts the flame, while the other half is separated therefrom by the in- The branch 2 is soldered.
